ATTACHMENT-HOLDER FOR SEWlNC-MACHINES.

SPECIFICATION forming part of Letters Patent No. 394,966, dated December 25, 1888.

Application filed December 27, 1887- Serial No. 259,090. (No model.)

To a whom it 71mg CON/0677b:

3e it known that I, JOHN M. GRIEST, a cit-izen of the United States, residing at Chicago, in the county of Cook and State of Illinois, 5 have invented certain new and useful Improvements in Sewing-Machine-Attachment Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the usual practice to secure sewingmachine attachmentsas guides, hemmers, binders, tuck-markers, &c.to the work-plate of the machine; but this practice is objectionable, for the reason that the attachments I 5 are liable to mar or wear away the ornamental japanned finish of the work-plate, so that when a new machine has been but slightly used in exhibiting it in the salesroom the work-plate becomes more or less scratched or marred, and the machine thus presents the appearance of a second-hand one. Furthermore, the attachments when attached to the work-plate are frequently more or less in the z bar the head A is drilled for the reception of way of the operator.

tachments to the work-plate of the machine The objections incidental to securing at- 1 have in some instances been partially avoided by securing the attachments to the presserfoot or presser-bar; but in such instances the 0 attachments have been more or less in the way, and were also subject to the rise and,

' thumb-screw, a, the inner end of which may fall of the presser -bars as the latter were moved by the action of the feed. It has also been proposed to support the attachments 3 5 from the machine-head by a bracket attached to the face-plate or outside of the head; but such a bracket was also more or less in the way and was unsightly, and it was therefore desirable to remove it when not in 40 use, so that it did not form a permanent part of the machine always in convenient position ready for use.

The object of my invention is to obviate these objections by providing an attachmentholding bar which is arranged within the head at the forward end of the overhanging bracket-arm of the machine. I also provide a convenientconstruction by which an attachment or a presser-foot may be detachably secured to its bar or holder.

In the drawings, Figures 1 and 2 are front and rear views, respectively, of the lower portion of a head of a sewing-machine provided with my improvements. Fig. 3 is a detail view of the lower ends of the attachment and presser-bars with the attachment and presserfoot removedI Fig. at is a detail sectional view to illustrate the preferred construction by which the attachment-bar is secured in the head in such a manner as to be vertically adjustable, so that it may be raised to be entirely out of the way when not in use. Fig.

5 is a detail horizontal section of one of the handled clamping-nuts. Figs. 6 and 7 are detail plan views of a hemmer and presserfoot, respectively, adapted for attachment to the holders.

A denotes the depending head at the forward end of a sewing-machine bracket-arm,

B the needle-bar, b the needle, 0 the presserbar, and c the presser-foot, all of which parts are or may be of the ordinary construction. Opposite the presser-bar rearward of the needlethe vertical attachment-holding bar D, the said bar being parallel with and beside the presser-bar and provided with a groove, d, into which enters a pin or small rod, cl, received in a horizontal hole drilled in the head A. The outer or forward end of the said hole is tapped for the reception of a abut against the pin or rod (1 to force the latter against the bottom of the groove d, and thus secure the bar D in place. lVhen the thumb-screw is loosened, the bar D may be raised or lowered until the upper or lower end wall of the groove (1 strikes the pin or rod d, when the further upward or downward movement of the said bar is arrested. The groove d is of proper length so that when the upper end wall thereof is in contact with the rod (1' the bar D is lowered to the proper place to receive the attachments and hold them in operative position, and when the said 5 'bar is not in use (as when no attachments are required for co-operation with the stitclr forming mechanism of the machine) it may be raised until the lower end wall of the groove d strikes the pin cl, so as to be out of IO- the way, and the thumb-screw (b will then be tightened to hold the said bar in its elevated position.

It is obvious that instead of using the pin or rod (1 the set-screw a might be made long enough to engage the groove of: the bar D without the intervention of the said pin or rod, the latter being used for the convenience of avoiding using so long a screw as would otherwise be necessary, and to prevent the bar from being released so that it will drop by inadvertentl y withdrawing the screw too far.

In order that the bar D may be securely held in place without set/tin the thtunb-screw inconveniently tight, I prefer to form slight recesses or indentations in the bottom of the groove (7, near the ends thereof".

In the drawings I have shown aheinmer, E, as being secured to the attaclnnent'liolding bar I), the vertical shank e of the hem mer hav ing at its top a horizontal portion, e, which is forked or slotted to embrace a shouldered and fiat-sided tenon, (1 near the lower end of the bar D, the said bar being tapped at its lower end for the reception of a screw, F, the head of which is provided with a handle, f, by which it may be turned, and with a series of threaded holes, f", into any one of which the handle f may be screwed.

The forked portion 6 of the shank of the hemmer is held between the head of the screw i and the shoulders formed on the bar I) by the tenon d". In adjusting the parts in place the screw 1? will be turned in far enough so that the portion 6' of the hemmer can just be inserted between the head of the said screw and the said shoulders, and a partial rotation of the screw will serve to secure the hemmer in place.

The head of the screw F is provided with the series of threaded holes f for the reeeption of the handle], so that when a proper adjustment of the said screw has been ascertained the said handle may be sm'ewed into that one of the said holes which may be in such position that the handle will be out of the way of the operator, or so as not to interfere with the presser-bar when the screw is tightened to secure the attat'ehment in place.

It will of course be understood that any other attaclnnent-as a binder, guide, quilter, tuck-marker, braider, &c.having a slotted holding-shank similar to that with which the hemmer E isprovided may be secured to the artaclnnent-bar I) in. the same manner that the hemmer is, as above described, the hem iner being merely one of several kinds of at tachments to be interchangeably used with sewing-machines.

I prefer to secure the presser-foot c to the presser-bar by a handled. screw, F, as above described, for holding the hemmer or other attachments, the shank c of the said presserjt'oot lntving at its top a forked horizontal portion, In other words, the shank of the presser-foot is of the same construction as the shank of the h ennner or other attachment, and the manner of securing the said t'oottoits bar is like that above described for the hemmer.

I do not herein claim, broadly, an independent attachment-holding bar secured within the head at the forward end of the bracket arm of the machine, this Feature ot'myinvention being reserved to my applicatimi, No. 250,080, filed simultaneously herewith; but

\Vhat I do claim herein, and d esirc to secure by Letters Patent, is

1. The ctmibination, with a depemling sewing-machine head, of a vertieally-adjustable attachmcut-holding bar within the said head and a securing device, as thumbsm-ew u, by which the said bar may be rigidly fixed in the said head in either a raised or a lowered. position, whereby the said bar is adapted to support attachments in operative position when desired and to be secured in a raised position out of the way of the operator when not in use.

The combination, with the head A, hav ing a horizontal hole or recess, of the vertical attachment-liar I), having the vertical slot (1, the pin d, loosely titted in the said hole and extend ing into said slot, and the thuinlrserew lapped in the outer llfil'idilll oi the said hole.

I). The combination, with a sewingqmlchinc head, of a vertical bar having a shmddered and flat-sided tenon at its lower end, an attz'tchmentor presser-lfoot having a shank with a forked horizontal portion at its upper end, a screw which is tapped through said tenon and the head of which. is provided with a series of threaded holes, and a handle threaded to be screwed into any one ol the said holes.

In testimony whereof I at'lix my signature in presence of two witnesses.
